Abstract
The research raise the question of the need to analyse and model the processes associated with the emission of the emergency-chemical hazardous substance (ECHS) in the urban environment. Because the assessment of the environmental pollution, the early and prompt prediction of the scale of contamination in the event of releases is the potent poisonous substance (PPS) into the environment in case of accidents (destructions) at chemically hazardous facilities remains an urgent issue. We emphasize that in order to ensure the life of any settlement, there is a need for the availability of drinking water that meets sanitary standards and hygienic rules. Chlorination is traditionally used in most of the country's settlements. To take timely measures to eliminate accidents with the emission of chlorine, the most accurate results of calculating the main indicators are necessary, such as the depth of the zone of contamination of PPS, the amount of the poisonous substance in primary and secondary clouds, the area of contamination, etc. The method of calculating these indicators is based on the use of reference tables and the coefficient method, which are convenient enough for the manual method. However, in emergencies, when serious threats to the life and health of people arise, and the situation can deteriorate rapidly, there is an acute shortage of time for a general assessment of the situation, making decisions on the organization of the rescue measures. It is obvious that the staff simply will not have enough time for scrupulous calculations, and a stressful situation, in addition, with a high degree of probability will provoke serious errors and inaccuracies.
Highlights
At the beginning of our study, we note that the potent poisonous substance (PPT) - chlorine is stored in containers, as a rule of a large volume
The mechanism of the thermal interaction between the hearth and structures depends on the relative position and geometric dimensions of the torch and the structures themselves
It is expedient to use the calculated parameters investigated by us when carrying out measures for the implementation of the protection of the civilian population outside the sanitary protection zones (SPZ) and caught in the emergency zone
Summary
At the beginning of our study, we note that the potent poisonous substance (PPT) - chlorine is stored in containers, as a rule of a large volume (for example, 2 containers of 0.9 tons each). The size of the center of the chemical damage depends on the scale and method of their application It is an emergency depressurization of containers with the emergencychemical hazardous substance (ECHS), meteorological conditions, as well as the terrain and its development. Note that back in the Soviet Union and earlier in the pre-revolutionary period in the history of the Russian state, much attention was paid to combating fires and especially to their prevention Many analysts analyzed these questions at the theoretical and practical levels: M. The attention was paid to the issues related to the extinguishing fires in the urban and rural areas on the pages of pre-revolutionary magazines For example, this is the Russian periodical "Fireman", and the Soviet edition "Fire business". The characteristics of the combustible load, the properties of the combustion products, the thermal characteristics of structures, as well as the nature of gas exchange affect the magnitude of the thermal interaction of the hearth with the structures [3]
